Longinus

The Longinus is an incredibly strong weapon which starts out hitting roughly 300HP/ shot. The reload is much faster than that of the crossbow and pixel cannon. While this weapon is only available through DLC it is worth noting that it is the 2nd strongest weapon in the game and maxes out at hitting an estimated 2,000,000,003 HP per shot at level 60. It is capable of one hitting most bosses during raids by level 15-20. The maximum level for this gun is 60.
